it is given that no of groups in a block=maximum no. of electrons can be occupied in the respective subshell . i cant understana so plz explain this
S-block consists of two groups.
That means in any period, there are two electrons which can fit in s shell.
Hence, from 2 to 7 periods, there are two groups in every periods for s-block.
Similarly, there are 10 groups for d-block as 10 electrons can occupy d-block.
Also, in the same way, there are 6 groups in p block as total 6 electrons can occupy p subshells.
